Update for April 12: Stephen Hawking and investory Yuri Milner have unveiled Breakthrough Starshot, an audacious $100 million research initative to develop technology for small, unmanned interstellar probes that could reach Alpha Centauri within 20 years of their launch.

Stephen Hawking will announce a mysterious new space exploration initiative Tuesday, and there's plenty of reason to think it will be a pretty big deal.

There's the famed astrophysicist's involvement, for starters, as well as the project's name — "Starshot." Furthermore, Hawking will make the announcement with billionaire entrepreneur and investor Yuri Milner, who is also bankrolling a 10-year, $100 million search for extraterrestrial intelligence (SETI) initiative called Breakthrough Listen.

Hawking was among a group of researchers who helped unveil Breakthrough Listen last July. (Milner is also funding a related project called Breakthrough Message, which will award prizes to people who help craft the best messages humanity could send to alien civilizations.)

That's pretty much all we know about Starshot — the project's name and the involvement of Hawking and Milner. A media advisory announcing the unveiling, which will occur Tuesday at 12 p.m. EDT (1600 GMT) during an event at One World Observatory in New York City, describes Starshot only as a "new space exploration initiative."

So we'll just have to wait and see what the project is all about. But there's one more intriguing tidbit: April 12 is the 55th anniversary of the first-ever human spaceflight, which was made by cosmonaut Yuri Gagarin on April 12, 1961, as well as the 35th anniversary of the first orbital mission of NASA's space shuttle program.

These two milestones are marked every year on April 12, during a celebration known as Yuri's Night . Milner was born in Moscow, and he has said he was named after Gagarin.
